What is mesothelioma and its primary known cause?

Mesothelioma is a rare and aggressive form of cancer primarily associated with exposure to asbestos. This cancer affects the mesothelium, which is the protective lining that covers many internal organs, particularly the lungs and chest cavity. The primary known cause of mesothelioma is inhaling or ingesting asbestos fibers, which can lead to long-term inflammation and damage to the mesothelial cells, ultimately resulting in cancer development.

While other respiratory illnesses may arise from different causes – such as smoking or air pollution – and various cancers can occur from chemical exposure, mesothelioma’s unique association with asbestos distinctly qualifies it as a separate and particular health concern. This specificity highlights the critical importance of understanding occupational hazards and the risks associated with asbestos exposure in environments where this material may be present.
